--- Comment #19 from Daniel Vetter <daniel at ffwll.ch> ---
Hm, the backlight controls are different, that could be it:

# intel_reg_write 0x61250 0x80000000
# intel_reg_write 0x61254 0x15cc07c6

Note that as soon as you do any brightness changes we'll overwrite these
settings again. So don't touch any brightness keys/settings and disable
autodimming for testing.

If it works please also test them individually to figure out which one is the
important change.
